Many specific details of the invention, such as structure, material, size, the processing work of device is described hereinafter
Skill and technology, to be more clearly understood that the present invention.But it just as the skilled person will understand, can not press
The present invention is realized according to these specific details.
Fig. 1 is the plane structure chart of the touch display panel of the embodiment of the present invention.Fig. 2 a and 2b are that the present invention first is implemented
The plane structure chart of the first electrode of touch display panel of example, second electrode.
Referring to Fig. 1, Fig. 2 a and 2b, which includes substrate 1, first electrode 201 on substrate 1,
Two electrodes 202.
Substrate 1 can be transparent panel or impermeable isotropic disk.Wherein, for transparent panel, substrate 1 can be rigid transparent panel for example

Coloring agent is added or is coated with dyestuff in vitro in transparent panel, and or per se with color material.Substrate 1 can also be other substrates
On transparent film layer, such as substrate 1 can be the dielectric layer or flatness layer in liquid crystal display panel.Specifically, liquid crystal display panel includes crystalline substance
Body pipe array substrate and colored optical filtering substrates, and substrate 1 can be the dielectric layer or flatness layer in transistor (TFT) array substrate.This
Outside, substrate 1 can also be the flatness layer in colored optical filtering substrates.Or it can be directly using colored optical filtering substrates as substrate 1.
Multiple first electrodes 201 and multiple second electrodes 202 are located at 1 top of substrate.Multiple first electrodes 201 are alternatively formed
First mesh shape.By Fig. 2 a it is found that the first mesh shape includes grid lines and several grids being made of grid lines.?
On Fig. 2 a, the first grid can be diamond shape, and in actual design, the first grid can also be square, rectangle or other have
The quadrangle patterns of symmetrical structure.First electrode 201 by rows, has interval, avoids first between adjacent first electrode
Electrode, which contacts with each other, leads to short circuit.Each first electrode is connected to external processing chip (on figure by the first lead 301 of side
It is not shown).In the embodiment shown in Fig. 2 a, lead-out wire is distributed in the two sides of first electrode, and the processing core with outside respectively
Piece connection.Therefore when carrying out the scanning of first electrode, two scanning signals can be obtained simultaneously, pass through the two scanning signals
The determination of touch location is carried out, it is in comparison, more accurate than by single scanning signal framing.But when actual design, it is
Can be only in the side of first electrode setting lead-out wire, i.e., first lead 301 is only arranged in the side of first electrode, to obtain
A single scanning signal is obtained, by single scanning signal framing touch location, although scanning accuracy is weaker than two sides lead-out wire
Scanning accuracy, but be also enough to position the position of touch point.
Multiple second electrodes 202 are alternatively formed the second mesh shape.By Fig. 2 b it is found that the second mesh shape includes grid lines

, bridge layer 403 is realized across the insulating layer 3 in first electrode between the first conductive layer in adjacent first electrode grid
Electrical connection then connects the grid lines that second electrode disconnects.In one embodiment, bridge layer 403 is electric across first
Insulating layer 3 on extremely is with diagonally connecting the first adjacent conductive layer；In another middle embodiment, bridge layer 403 across
The insulating layer 3 crossed in first electrode is to connect the both sides of the first adjacent conductive layer.
In the present embodiment, the first conductive layer 401, the second conductive layer 402 and bridge layer 403 can be aoxidized using indium tin
Object or indium zinc oxide are constituted, and the translucency of touch display panel can be improved using indium tin oxide or indium zinc oxide.
In the above-described embodiments, first electrode is driving electrodes, and second electrode is induction electrode or first electrode is to drive
Moving electrode, second electrode are induction electrode.Driving electrodes are used for column scan for row scanning, induction electrode.As long as therefore setting
The corresponding ranks relationship for designing touch display screen of timing.Side includes that the electrode of two lead-out wires is best used as capable scanning
Electrode be suitble to that two lead-out wires are arranged in width direction this is because touch display screen is generally wider.
In conclusion the touch display panel of the embodiment of the present invention includes substrate and multiple first electrodes on substrate
With multiple second electrodes, multiple first electrodes are alternatively formed multiple first grids, and multiple second electrodes and multiple first electrodes are handed over
Same layer setting is pitched, and second electrode is disconnected with first electrode crossover location.Touch display panel further includes multiple conductive layers, if
It sets in the first grid and at least covering part is located at the second electrode in the first grid, in the first at least partly adjacent grid
Conductive layer be connected with each other；Insulating layer, at least projected area of the bonding pad of covering adjacent conductive layer on the first electrode.It adopts respectively
With insulating layer and conductive layer covering first electrode and second electrode, first electrode and the not oxidized corrosion of second electrode can be protected,
Improve the corrosion resistance and reliability of product.
Further, first electrode is completely covered by insulation using insulating layer, therefore conductive layer can be used by second electrode
Grid lines disconnection place connection, with the prior art using conductive connecting or compared with being conductively connected grid, touch-control
Induction precision is higher.
In the present embodiment, insulating layer extends along the grid lines of first electrode, is realizing being completely covered absolutely for first electrode
While edge, reduce the area of insulating layer, reduce the light loss of touch display panel simultaneously, first electrode and second electrode use
Same layer mesh metal intersection is made, and the touch display panel phase of different metal layer is located at existing first electrode and second electrode
Than reducing one of production routine in process of production, being conducive to the production efficiency for improving touch display panel.
The embodiment of the present invention provides a kind of touch-control display module comprising above-mentioned touch display panel simultaneously, is, for example,
The portable electronic devices such as tablet computer, smart phone, laptop, handheld device or digital camera.Alternatively, can also
To be the device with large touch screen such as ATM, arcade game or touch-control television set.The touch device also wraps
A display screen is included, touch display panel is embedded into display screen.It specifically, can be with on-cell (upper laminar) or in-cell
(inner layer formula) is embedded into display screen.Touch-control sensing route is made in liquid crystal display panel thin-film transistor array base-plate by in-cell
On pixel inside, and on-cell is then surface layer or the bottom that touch-control sensing route is made in color filter glass substrate,
That is touch-control sensing route is made between color filter glass substrate and polaroid or is made in colorized optical filtering
Between sheet glass substrate and liquid crystal layer.Therefore the induction line of the touch display panel of in-cell and on-cell formula is because by base
The protection of glass sheet and it is safer, and be more convenient for realizing the slimming of touch control display apparatus and lightweight.
In addition, the touch display panel can also improve the resistance to corrosion and reliability of product, and increase flexible circuit
Plate (FPC) and the adhesive force for binding area (bonding pad).
In the present specification, "lower" refers to drawing the opposite of the direction outside inductive layer closer to lead-out wire in a column direction
Concept, "upper" refer to the relative concept for drawing inductive layer outside direction further from lead-out wire in a column direction.
